IMPROVEMENT IN BEDSTEAD-FASTENINGS.

Specification forming part of Letters Patent No. 162,039, dated April 13, 1875; application filed June 18, 1874.

To all whom it may concern:

Be it known that I, EDWARD DEETZ, of }?hiladelphia, Pennsylvania, have invented an Improved Bedstead-Fastening, of which the following is a specification:

The object of my invention is the ready and secure attachment of the rail of a bedstead to the post, and its ready withdrawal from the same, an object which I attain by the device illustrated in the vertical section, Fig. l, and sectional plan, Fig. 2, of the accompanying drawings.

In the post- A is cut a recess, a, the shape of which will be best understood by referring to the perspective view, Fig. 3, the recess being enlarged above, from theltop a@ to the point y, where it is suddenly contracted in front, but not at the back, a chamber, mi, being formed behindI the contracted portion of the recess for the reception of the casting B, shown in perspective in Fig. 4, this casting, on which are two inclinations, m m, strengthened by side flanges b b, being introduced into its place by first passing it into the enlarged upper portion of the recess, and then dropping it into the lower chamber.

The portion D of the fastening has a web, d, with a cylindrical termination, e, and is secured to the rail in the following manner: A hole of the diameter of the cylindrical tern'iination e is first bored in the under side of the rail, and then a mortise, c, is so formed in is elevated so th at its projecting portion e shallv pass into the hole. A plug, j', is then driven into the latter, so as to bear against the lower end of the cylindrical termination of the web, and prevent its detaehmentfrom the rail until the plug is withdrawn. On the head h of the portion B of the fastener are formed two inclined shoulders, t', which bear against the inclinations m on the casting B. The latter is fitted into the chambered recess of the post,.in the manner described above, so that the greater the pressure on the rail the more secure will be the fastening. In order to 'detach the rail from the post, all that is necessary is to elevate the former until the head h of the portion D of the fastener coincides with the upper and widest portion of the recess a of the post, when the heads can be withdrawn from the recess. reconnecting the rail to the post will be readily understood without explanation.

I do not claim, broadly, a T-headed projecy tion on a rail adapted to a recess contracted toward the lower end in the post, as this is common in bed-fastening devices, but I claiml. rlhe combination of the rail and its Aiianged projection D, and the post A, having a recess, a., a chamber, x', contracted at the front and forming a continuation of the recess, anda casting, B, tting the chamber, and provided with inclines m m and flanges b b, all as and for the purpose described.

2. Ihe rail, having a 1nortise,c, and a recess extending above and belou7 the mortise, at right angles thereto, in combination with the casting D, extending into the mortise and having a projection, c', which is maintained within the upper portion of the recess by a plug, f, tting the lower portion, as set forth.

In testimony whereof l have signed my name to this specification in the presence of two subscribing witnesses.

EDWARD DEETZ.
